Chat GPT for Unity

This Unity script allows you to send chat requests to OpenAI's GPT-3 API and receive responses. It is composed of a single static class, ChatGPTApi, which has the following features:

• A SendChatRequest function that sends a chat request to the GPT-3 API and invokes a callback with the response.
• An OnMessageReceived action that you can subscribe to in order to receive chat responses.
• A token field that you should set to your OpenAI API key in order to authenticate your requests.

Usage

To use the ChatGPTApi class, you will need to do the following:

1. Obtain an API key from here.
2. Set the token field to your API key:

private static string token = "TOKEN";

3. Subscribe to the OnMessageReceived action in order to receive chat responses:

ChatGPTApi.OnMessageReceived += OnMessageReceived;

void OnMessageReceived(ChatGPTResponse chatResponse) { // Handle the chat response here }

4. Create a ChatGPTRequest object and send it to the GPT-3 API using the SendChatRequest function:

ChatGPTRequest chatRequest = new ChatGPTRequest { prompt = "Hello, how are you?", max_tokens = 1024 };

ChatGPTApi.SendChatRequest(chatRequest);

Notes

• The SendChatRequest function sends a POST request to the OpenAI API and expects a JSON response.
• The ChatGPTRequest and ChatGPTResponse objects are serialized and deserialized using Newtonsoft.Json. You will need to have the Newtonsoft.Json package installed in your Unity project in order to use this script.
• The SendChatRequest function uses Unity's UnityWebRequest class to send the request and receive the response. It is asynchronous and invokes a callback when the request is completed.
